First question is: Will there be ways to customize equipment in the future other than Dyeing (end game gear included). At the moment, I feel that there is very few diversity between equipment for a character where one has to choose between Dungeon or Allagan Tomestones or Crafter equipment (except end game, crafted equipment doesn't apply here).

I would gladly see Materia affixing or a quest such as the Animus that you do objectives to raise a stat on a piece of equipment (but limited so that it creates diversity between equipment X from player A and the same piece of equipment from player B).

Second question is: Will we see new specs or roles introduced to the existing class/jobs. A Tank that can switch to a more Damage dealing stance or a Dps that in some situations will act as a Tank.

I love my Paladin but when queuing Titan or Ifrit (not the extreme versions) for example and I end up being the Off Tank, I feel that I am only there for decoration or the "oh shit" moments.
